pensive to construct and cumbersome in size, shape and appearance. By my improved construction, however', the bearing may be inclosed within a small s ace, and the thrust pressures put upon it ta en u by surfaces near the axis of the shaft with w ich it coacts.

In thrust bearings arranged for large shafts or for very high ressurc I prefer to use a great number of tfie studs 22, but for moderate pressures and where conditions will so permit, I prefer to employ only three studs, as shown in the drawing.

What I claim is:

1. In a thrust bearing, the combination of a spider comprising a plurality of bosses, a stud extending from each of the bosses, a spherical roller having a hole through its center mounted on each stud, said hole being substantially greater than the diameter of the stud, and a plate fastened to the end of the stud; said boss and plate being arranged to prevent undue lateral displacement of the roller and the rollers arranged to sustain all the load on the bearing, the diameter of each of said rollers being greater than its length.

2. In a thrust bearing, the combination of a spider comprising a plurality of bosses, a stud formed integrally with the spider extending from each of the bosses, a spherical when having a hole through its center mounted on each stud, said hole being substantially greater than the diameter of the stud, and a plate fastened to the end ;of the stud; said bosses and plates being arranged to revent undue lateral displacement of the rol ers.

3. In a thrust bearing, the combination of a spider comprising a plurality of bosses, a stud extending from each. of the bosses, said stud having a shoulder at its end, a'plate fastened to the stud against said shoulder and a spherical roller mounted with clearance on each stud between the boss and the plate, said boss and plate being arranged to prevent undue lateral displacement of the roller, and the rollers arranged to sustain all the load on the bearing, the diameter of each of said rollers being greater than its length.

4. In a thrust bearing, the combination of a spider comprising a plurality of bosses, a stud extending from each of the bosses, said stud having a shoulder at its end, a spherical roller having a hole through its center and mounted on each stud, said hole being subto sustain all the load on the bearing, their diameter of each of said rollers being greater than its length.

5. In a thrust bearing, the combination of a hub having a plurality of bosses, a stud extending at right-angles from each one of the bosses, a )late fastened to the end of each stud, and a plurality of rollers having spherical faces mounted on each stud between the boss and the plate.

6. In a thrust bearing, the combination of a hub, a stud extending from the hub, a plurality of rollers of different lengths mounted on the stud, and two disks in contact with the faces of the rollers.

7. In a thrust bearing, the combination of a hub, a stud extending from the hub, a plate fastened to the stud, a plurality of rollers of different lengths mounted on the stud, and tWo disks in contact with the faces of the rollers.

8. In a thrust bearing, the combination of a central hub, three studs extending radially from the hub, a plurality of rollers having spherical faces mounted on each of the studs, a plate fastened to the end of each stud, and two flat disks in contact with the faces of the rollers.

9. In a thrust bearing, the combination of a central hub, a plurality of studs extending radially from the hub, a plurality of rollers of different lengths mounted on each stud, said rollers having flat ends and spherical faces, a late fastened to the end of each stud, an tWo flat disks in contact with the faces of the rollers.

10. A thrust bearing comprising a lurality of radially disposed studs, a plura ity of spherically-faced flat rollers mounted upon each of said studs, each of said rollers being at a different distance from a-central axis, a disk arranged to transmit pressure to the rollers, and a disk arranged to sustain the pressure.

1.1. A thrust bearing comprising three equally spaced radially disposed studs extending at right-angles from a central axis, a plurality of spherically-faced [lat rollers mounted upon each of said studs, each of said rollers being maintained at a different distance from said central axis, a flat faced disk arranged to transmit pressure to the rollers, and a flat faced disk arranged to sustain the pressure.

12. A. thrust bearing comprising three equally spaced radially disposed studs ex tending at right-angles from a central axis, a plurality of spherically-faced flat rollers of differentlengtl'is mounted upon each of said en L675 studs, each of said rollers being maintained at a different distance from said central axis, a flat faced disk arranged to transmit pressure to the rollers, and a flat faced disk arranged to sustainthe pressure.

13. In a thrust bearing, the combination of a hub, a plurality of studs extending radially from the hub, a plurality of separate rollers mounted uponeach one of the studs, said rollers having flat ends and spherical faces, a disk arranged to transmit pressure to the rollers, and a disk arranged to sustain the pressure,

14. In a thrust bearing, the combination of a hub having a plurality of bosses, a stud extending at right-angles from each one of the bosses, a plurality of se arate rollers having flat ends and spherical aces mounted on each stud, and two disks in contact with the faces of the rollers.

15. In a thrust bearing, the combination of a hub having a plurality of bosses, a stud extending at ri lit-angles from each one of the bosses, a p ate fastened to the end of each stud and a spherical roller haying fiatends mounted on each stud, between the boss and the plate, and two disks in contact with the faces of the rollers".

16. In a thrust bearing, the combination of a shaft, a fiat-faced disk arranged to'ro-' ,tate therewith, a stationary flat-faced disk, plurality of rollers of equal diameter each forming an equatorial section of a sphere interposed between the flat faces of the disks and arranged to sustain all the load on the bearing, and means for holding each of the rollers at a different fixed distance from the axis of the shaft.

17. In a thrust bearing the combination of a spider comprising a hub and a plurali ty' of studs extending therefrom, a spherical roller having a hole through its center mounted on each stud, and a plate fastened to the end of the stud, the distance between the hub and the plate being substantially greater than the length of the roller; said hub and plate being arranged to prevent undue lateral displacement of the roller, and the eus'rar RnNNnnrEaT "Witnesses:
